Nagase Takahama Iseki (Ruins) is a vast complex of archaeological sites spanning from the Yayoi Period to the Middle Ages, where a number of significant discoveries have been made. The most remarkable of these is the unearthing of a large number of haniwa (clay figurines) from locations outside of burial mounds. These early haniwa are shaped like items such as armor, houses, shields, and indigo plants. (Typically, haniwa are in the form of humans or animals.)
